Abstract
The utility model discloses a rotatable water-cooled cable, which comprises a copper joint, copper stranded wires, a sealing ring, balls, a rotary sleeve and a differential spring. The balls are embedded in a rolling groove at the outer edge of the copper joint and then fixed by a slotted screw; the rotary sleeve is sleeved at the outer edge of the cylindrical part of the copper joint through the balls; the sealing ring is arranged between a groove of the copper joint and the rotary sleeve; the differential spring is arranged at the center of a plurality of copper stranded wires so as to lead the copper stranded wires to wind around the outer edge of the spring; and the copper stranded wires are plugged into a copper joint port. The outer edge of the rotary sleeve also can be sleeved with a rubber hose used for protection. The rotatable water-cooled cable has good cooling effect, and can rotate with the large current jittering, therefore the strain of the cable inner core by the electrodynamic force and the breaking of an outer sleeve are avoided, the service life of the cable is prolonged, and the installation and processing are simple.
Description
Technical field
The utility model relates to the electric power transfer field of metallurgical electric furnace, specifically is a kind of rotatable water-cooled cable, is mainly used in metallurgy, converter and transmits a kind of beaming type water-cooled cable with big section that big electric current uses.
Background technology
Existing beaming type water-cooled cable with big section has the following disadvantages:
1, existing water-cooled cable, installation and processing is more loaded down with trivial details.This is because existing water-cooled cable because there are intrinsic angle in deadweight and mounting plane own, makes construction bolt be difficult to make cable plane and connector plane fastening to prizing
2, general water-cooled cable cannot rotate with it when big electric current is shaken, and causes the cable inner core to be sprained easily, and outer tube fractures.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of rotatable water-cooled cable is provided, this water-cooled cable can not only transmit big electric current, and cooling water flow is reasonable, every sub-thread cable, all cooled off fully, and can when big electric current shake, can rotate with it, thereby prolonged useful life of cable, avoided electric power to the cable inner core, spraining of outer tube, fracture, long service life is installed, processes simple.
A kind of rotatable water-cooled cable described in the utility model, comprise copper sleeve, copper stranded conductor, sealing ring, ball, rotary sleeve and differential spring, described ball is embedded in the rolling groove of copper sleeve outer rim, spacing in groove by interrupted screw again, rotary sleeve is enclosed within on the column part outer rim of copper sleeve by ball; Sealing ring is located between the groove and rotary sleeve of copper sleeve, and the differential spring is located at the center of multiply copper stranded conductor, and copper stranded conductor is twined along its outer rim, and copper stranded conductor inserts in the copper sleeve interface.
Above-mentioned rotary sleeve outer rim can also be with the rubber tube of protection usefulness.
Compared with prior art of the present utility model, its advantage is:
1, the utility model rotatable water-cooled cable good cooling results can be rotated with it when big electric current shake, thereby avoided electric power that the cable inner core is sprained, the fractureing of outer tube.
2, can rotate owing to the utility model, so it is construction bolt is very convenient, time saving and energy saving.
3, prolonged the useful life of cable.
4, install, process simple.

Embodiment
Below in conjunction with most preferred embodiment the utility model is further set forth:
As depicted in figs. 1 and 2, rotatable water-cooled cable described in the utility model, comprise copper sleeve 1, pipe collar 2, copper stranded conductor 3, sealing ring 5,11, ball 6, rotary sleeve 7, rubber tube 8 and differential spring 9, wherein: ball 6 is embedded in the rolling groove of copper sleeve 1 outer rim, spacing in groove by interrupted screw 12 again, rotary sleeve 7 is enclosed within on the column part outer rim of copper sleeve 1 by ball 6; Sealing ring 5,11 is located between the groove and rotary sleeve 7 of copper sleeve 1, and differential spring 9 is located at the center of multiply copper stranded conductor 3, and copper stranded conductor 3 is twined along its outer rim, and copper stranded conductor 3 inserts in copper sleeve 1 interface 4.Rotary sleeve 7 outer rims are with rubber tube 8, and pipe collar 2 is used for rubber tube 8 fixing.In copper sleeve 1, also be provided with the cooling water runner 10. that is communicated with each strand copper stranded conductor 3
Rotatable water-cooled cable makes copper stranded conductor 3 twine along its outer rim because differential spring 9 is located at the center of multiply copper stranded conductor 3, even the position also remains unchanged when operation.The in-core wiring is reasonable, and CURRENT DISTRIBUTION is even, and lead is utilized effectively.Cooling water flow is reasonable, and every sub-thread cable is all cooled off fully.The cable two ends are plain joint, connect simple and reliablely, and water-cooled are arranged in the joint.Copper stranded conductor and copper sleeve form with a crimping of specific process, have avoided the various disadvantages of bringing with welding method.
